I shipped a package to Spain on 2-25-08 and the buyer said have not received it yet. I have a customs decleration number, but when I enter it at USPS.com it just shows that the package was accepted. When I asked USPS about delivery confirmation they said they don't do it for international shipments since once it leaves the US. I'm just wondering if there is any way to tell if it is sitting in customs in Spain. Or is there any way I could contact customs in Spain.
